In the drawing, to wifichdetailedreference WI1 now be made, I have shown'a ,closre device of the type disclosed in my copending application V--Serial No. 549,956,fi18d July 10, 1931. AS disclosed in saidapplication, my closure device is of the -bayonet type andcomprises, amember ha.ving aiiopening to beciosed, such as the tubular filler neck10, and a. closure 11 connected thereto by ineans of the hin'ge iinka.ge12. The tubular member to be closed may be secured to 1 the wall of afuel tank, radiator, or otherreceptacle, and is provided at ,its outerehd With a laterally extending flang13 forming onepart of a bayonetlocking device and also provding a seat} for the ga.sket 14.

'Ihe closure itself may be of any appropriate construction and, as shownin this instance, comprises a. body having a shell composed of Olit6land inner sheet metal walls15 and 16 which walls are secured together inany suitable manner, With,a 7chamber threbetween. A locking spring 18,which is secured to the inner vva1ll6, as by meazis'of the rivets 19, is:provided with oppositeiy .extending resilient cani fingerS 20. Thesecam fingers are shaped and. arranged to pass through the notches oropenings 21 of the flange 13, and to cooperate'With the under surthesecuring portion 27 is mounted therein,the

counterbore 32 having a diameter exactly egual the closure and thet'ubulanme'mber. Thehin'ge iinkage,as shovvn in this instance,

comprises a'bracket 22 secuiedto the wall of the tubular" n ember, and alink 23 pivotd atone of 0 its enti; to the bracket 22 and at its othrend to al bracket 24. Thel'altter bracket. s, in mm,

'Ti e, pvotakconnection betv veen the wa,ll 16 ;nd

the'0utei wall 15, to-receivethe securing stem or portion 27 of thedisplay. I have also found that,in drilling this hole through the pivotmembei 25, grezit caremust be exercised to locate the hoie exactly onthe axis of the pivot member so that the opening being formed wiii notbreak through the wall of this member. It isalsoimportoni; that theopening to be formed in the pivot memb'er be of the proper size so tha.twhen liquidi of the container wiil not securing porti0n.

As shovvnin the drawing, the pivot member 25 is constructed with ashouldered stem portion 28, upon which thehirige member or bracket 24 ise scape arpund this pivoted, a'nd a head portion 29 for retairing themember' 24 upon the stem portion. F01 ,con-

veniently securing the pivot memberto the wall 16 of the clo'surefIconstruct this memberrin the form of a hollow rivethaving a sleeveportion extending through the wall 16 and riveted overto -form the head30. I For the purpos of indicating the exact location for an openingthrough the pivot member, should one be desiied for the securingportieri of a display, I provide the drill centeri'ng recess 31, as'shown in Fig 3 of the 'dravvng. In additidnto-this drill centering re-.cess, which is located xactly on the axis of the pivot mmber, I providea shallow depression or having a drill centering recessin the hea.dthereof, and also having a counterbore indioating.the

maximum size o! dril1 which may be DSed-withtighte ned, I" prefei toprovide the sec uiing stem purpose, as shown in Fig. 1, itmay'be.de'sirable out brea'king-throughof injuring the stempertion of thepivot member.

When the owner'of the closure device desires to apply a,n ornament, orother display device,to the closure, it is only necessary tor to dr-illoutwardly through the pivot membei 25' MM through the outet wali 15;:Durng. this opera tion, a, drill is employed of not largo? diameter thanthe diameter of the counterborey 32; whih drill isbentered for thedrilling operation in the recess 31. Although the opening initiallyormed in the wa.1l 15 is ci the same diameter a s the hole drilledthrough the rivet, this opning may subsosize have been drilled throughthe pivot mmbr andthe wal1 15', the securing;portion oftliddis play;device iS nserted through these openings and may be retained agai nst withdrawal by means of th nuts 33, or any othopsitab'le' securing means.

Instead of employing an integrati sh0ulde r for this toprovide the tubular spacr'35-shoWn in Fig. 5, in which case the secuiingstm 27 may be of uniform size throughout i ts leng'th. vWhen such aspacer is 'emplcjyed, this member extends between the under side of thedisplay 26' and the I t Will now berg'dily seo that I have prvided animproved form of hinged closure devioe upon whic h an omameht or displaymay be rea.dily mounted with' a securing portico extending through thehinge pivot member of the closure.

Moreover, it will be seen that by my invention I have provided simpleand reiiable means for accu'rately indcating the size and location ofthe open.ing to ,be drilled for the'securing portion of thedisplay,thereby eliminating'the d2 mger of the closure device being ruined by animpioperly drilled hole.

While I haveillustrated and described my invention in a. detailedmanner, t should be understod, however, that I do not intend to 1imtmyself toth e precise details of construction and arrangements of ,partsillustrated and described, but rsga.rd my invention as ncluding suchhance; and modifications as do not involve a depaxture7fronthe spirit ofthe invention and the scope of the appended claims. quently be enlargedto accommodate a.ny size of securing portion; After openi1igs "of'prop.er

Ha.ving thus described my invention, I claim:

' 1.The combnation with a radiatoxf c.p having outr andfinner Wal1s Witha chamber therebetween, of mans formountng a. display on said onopposite sids. of said innr wall, the head porti0n of said member whichis most remote from the outr wal1 having a recess therein for indicatingthe location a.nd size of the opening' in said hollow stem portion.
